[Towertalk] Coax Surge Protectors that pass DC

Don,
Do these units have a DC short to ground at the antenna end? In other
words, do you use a large inductor so that static is bled off the center of
the coax. If so, then even though the supressor may pass DC, you still
can't run bias through it as the original poster wanted to do.
If it's just a gas tube and no center pin connection to ground other than
that, then he's all set and besides, you make a good product.
